Problems solved by technology

[0005] The above-mentioned scheme has made some improvements in bass enhancement, but the problem it does not solve is: in the existing KTV sound system, if the above-mentioned circuit or system is integrated, when the user sings, the heavy bass will cover the Or affect the human voice. If the above-mentioned circuit or system is not integrated, then if the user just wants to listen to the song quietly, he will not be able to get a perfect and shocking sound experience.
In such a very contradictory situation, the user often needs to call the tuner to solve it, but after the tuner frequently debugs a sound system, the sound system in the room becomes more and more chaotic, which seriously affects the user experience
[0006] And traditional circuits and systems cannot realize the simplification of the device and the convenience of system installation

Embodiment 1

[0042] Such as figure 1 As shown, a bass compensation method for an audio system, the method specifically includes: judging whether the microphone is on; if the microphone is on, then mixing and outputting the music and the sound recorded by the microphone; if the microphone is off, then extracting the low frequency in the music signal, and output this low-frequency signal mixed with music.

[0043] Specifically, judging whether the microphone is on is based on the electric frequency signal in the microphone amplifier circuit. If the electric frequency signal in the microphone amplifier circuit is in the state of 0.1-5V, it means that the microphone amplifier circuit has received the signal from the microphone. .

[0044] When the microphone is turned off, the specific processing method is as follows:

[0045] S11: extract the low-frequency signal in the audio signal of the music through the DSP digital processor, and perform parametric equalization processing;

[0046] S12: ...

Embodiment 2

[0057] This embodiment provides a bass compensation circuit for implementing the audio system of Embodiment 1, specifically as figure 2 As shown, it includes a microphone amplifier circuit 1, a controller 2, and a DSP digital processor 3;

[0058] Described controller is connected with microphone amplifying circuit 1, DSP digital processor 3 respectively, and described microphone amplifying circuit 1 is connected with DSP digital processor 3;

[0059] The microphone amplifying circuit 1 is used to output the sound recorded by the microphone to the DSP digital processor 3, and to output the electric frequency signal for closing and opening the microphone to the controller 2; necessary, the microphone amplifying circuit 1 and The DSP digital processor 3 is also provided with a digital-to-analog conversion module for converting analog signals into digital signals.

[0060] Described controller 2 is used for judging whether microphone is opened according to electric frequency si...

Abstract

The invention discloses a bass compensation method for a sound system. The method specifically comprises the steps that whether a microphone is turned on or not is judged; if the microphone is turned on, music and sound recorded by the microphone are mixed to be output; if the microphone is turned off, low-frequency signals in the music are extracted, and the low-frequency signals and the music are mixed to be output. By means of the bass compensation method for the sound system, the mega bass effect can be adjusted according to user demands, and sound effects in different user demand states are achieved. The invention further provides a circuit for achieving the base compensation method. The circuit has the above advantages and also has the advantages that the matched sound system can be effectively simplified, and the installation difficulty is lowered.

Description

technical field [0001] The invention relates to the field of KTV audio equipment and control methods, in particular to a bass compensation method for an audio system, and simultaneously the invention also discloses a circuit for realizing the method. Background technique [0002] In the prior art, those skilled in the art have done some work on improving the bass enhancement of the sound signal, such as Chinese patent application CN200810300105.3, which discloses an audio compensation device, including a left input terminal and a right input terminal. The input end is used to respectively receive left and right channel sound input signals output by a player, and a left output end and a right output end are used to respectively output the left and right channel sound input signals to an earphone. The audio compensation device further includes a frequency compensation unit. The frequency compensation unit is coupled between the left and right input terminals and the left and ...
